Answer:

y = -4/3x + 2

Step-by-step explanation:

Point slope form is this:

y - y1 = m (x - x1)

Where m is the slope. y1 and x1 are where you put your coordinates.

so now we just plug it in.

y - (-2) = -4/3 (x - 3)

We should clean it up in order to make it look like this equation:  y = mx + b

y + 2 = -4/3x -4/3(-3)

y + 2 = -4/3x + 4

y = -4/3x + 2

The reciprocal of 150 will be 1/150.

We have a marine center has 150 parking spaces in front of its building.

We have to find the reciprocal of 150.

The reciprocal of a number is a number such that the product of both the numbers is equal to 1. Mathematically, if the original number is a, then its reciprocal will be 1/a , such that -

a x 1/a = 1

According to the question -

Let us assume that  A = 150

Now, from the definition of reciprocal, the reciprocal of A will be -

1/A. Therefore, the reciprocal of 150 will be = 1/150

Hence, the reciprocal of 150 will be 1/150.

The percentage increase in length is 22.5%.

Given parameters are;

The area of the square garage is 314 ft.²

The area of the new garage has 50% more space

Required;

Initial side length:

The initial side length, given to the nearest tenth, s, is the square root of the area, A, given as follows;

s = √(314 ft.²) ≈ 17.7 ft.

New Side length:

The side was increased by 50%, to give,

314 + 0.5×314 = 471

The new area of the garage = 471 ft.²

The side length of the new garage, s = √(471) ≈ 21.7 ft

The side of the garage now is 21.7 ft.

Percentage increase in length:

The percentage increase is given as follows;

% increase in length

= new side length - old side length / old side length * 100  

= 21.7 - 17.7 / 17.7 *100

Saturn from Earth, it looks like it has a diameter of 20 μm.

d₁=20μm

Through a telescope, the diameter looks 9,000 μm long.

d₂= 9,000 μm

magnification scale = d₂/d₁

                                =  450/1

magnification scale  used was 450:1

A scale factor is a number that can be used to adjust the size of any geometrical figure or object in relation to its original size. It's used to draw the enlarged or reduced shape of any given figure, as well as to calculate the missing length, area, or volume of an enlarged or reduced figure. It should be noted that the scale factor only affects the figure's size and not its shape.

A scale factor is a number or conversion factor used to adjust the size of a figure without changing its shape. It is used to enlarge or reduce the size of an object. If the dimensions of the original figure and the dimensions of the dilated (increased or lowered) figure are known, the scale factor can be determined. A rectangle, for example, has a length of 5 units and a width of 2 units. If we raise the size of this rectangle by a factor of two, the sides will become 10 and 4, respectively. As a result, we can use the scale factor to determine the dimensions of the altered figures.

Step-by-step explanation:

[tex].4\bar{2}[/tex]  means the 2 repeats till infinity
[tex].4\bar{2}[/tex]  = .4222222222.....

To convert to fraction just take the first three decimal place digits 422 and divide by 1000 to convert to fraction

[tex].4\bar{2} = \frac{422}{1000}[/tex]

Dividing numerator and denominator of this fraction by 2 gives
